DAVID surnnntann BADENOCH, or LEICESTER, ENGLAND MEANS non coimno'rrne CHANNEL Application filed October 19, 1929, Seria1 No. 400,866, and in Great Britain October 20, 1928.

This invention comprises a newer improved means for connecting channel members and other members of curved section,

and. has particular, although not exclusive 1 reference to means for providing a connection or jointing between the separable parts of a pleasure boat of the type comprising two or more channel or bow-sectioned parts provided with transversely extending seats, the said parts being adapted to be taken apart and packed in a confined space for transportation.

The object of this invention is to provide a simple and ellicacious liquid-tight connecting means for channel or other similarly sectioned members and more particularly to provide an improved readily releasable wator-tight connection for the separable parts of pleasure boats of the above mentioned type.

The present invention consists in a method of connecting curved members wherein the said members are located or positioned between a plurality of curved retainingmembers at least one of which is a leaf spring and means such as bolts and screws for clamping the said curved members together.

The connecting means may comprise a curved member whichis substantially rigid and is located at the exterior of the channel or'curved members being connected, a plu- :rality of superposed curved springs located interiorly of the said channel members and havinga tendency to bow outwardly and one or more screwed bolts orthe like passing from the outer connecting member through the members being connected and the interior leaf springs, thesaid one or more bolts functioning to cause the interior springs to press the said channel members together and against the nterconnecting member to pro vide a liquid-tight joint between the said members.

The invention is particularly applicable for connecting the curved transverse end frame members of a sectional pleasure boat comprising a plurality of boat sections each of which embodies curved transverse end frame members spaced apart and connected by longitudinal frame members, the said framemnmnnns sno'rrons PATENT OFFICE work supporting a covering of sheet metal, plywood or other sheet material and the several sections being connected by means of the present invention to constitute a boat.

For the purpose of enabling this invention 33 to be more: readily understood, reference will now be made to the accompanying drawings wherein r Fig. l is a cross sectional elevation illus trating two channel members connected to Cl) gether by means according to the present invention.

Figs. 2 and 3 are part-sectional elevations of the front and rear parts respectively of a sectional pleasure boat the separable sections of which are connected by means according tothe present invention, and

Fig. 4: is a cross-sectional elevation on line AA of Fig. 2 looking in the direction of the arrows.

In the simple form of the invention illustrated in Fig. 1, two channel sectioned members 1, 2 are connected in a readily releasable liqurd-tight manner by means of a substantially rigid curved bar or strap 3 extending around the exterior of the outer channel member 2. A plurality of superposed lea-f springs 41, conveniently held together by means of stirrups or straps 5 and a bar (1, are provided in the interior of the inner ehannel member 1, the said sprin s having a normal tendency to bow outwardly or straighten themselves. i

Passing through registering holes provided centrally in the outer strap 3, the channel I members 1 and 2, the leaf springs 4 and the supporting bar 6, is a bolt member 7 pro vided with a screw thread along its upper parts. The lower extremity of the bolt '7 is provided with a tapering or part conical enlargement 8 adapted to fit tightly in the hole provided centrally in the outer strap 3, which hole is preferably tapered to conform with the said enlargement. A washer 9 and spacing sleeve 10 may be provided encircling the upper parts of the bolt 7 and interposed between the bar 6 supporting the springs and a nut 11 screwed upon the said bolt, the said nut convenientlyhaving enlargements or projecting parts by means 103 of yvhich it may be tightly screvved upon the 'shouldfbe arranged. normally to bow. slightly efiicient' liquid-tight connectionzr for the said.

bolt by hand. 7

' Upon the parts being assembledandthe nut 11 tightened upon the bolt 7, the channel members 2 are tightly clamped between the leaf springs. 4' and-the outer strap: and an channel members is provided.

If the outer member?) isprovided atall resilient or' flexible, it"ispreferab'le that sameinvvard. 7

if desired, the substantially nd strap member. may besprovided. in the interiorrof the channel members and a plurality of leaf springs may be positioned atthe; exterior thereof? In. other words,tlie arrangement necteda and it. will be understood that in. such modification the interior 's-pringswill be arranged andtempered normally to spring-outwardly and thexexterior springsv arranged normally to spring: inwardly,

The, superposed leafi springs'ar-e preferably; of slightly varying thickness.

In another modification, a;. single leaf 5 spring; be substituted for the plurality of superposed-I leaf springs/t and instead of the parts being clamped together by means of. aanutscrewed uponia centralbolt, the said bolt. may have a screw thread located withinan internally threaded hole'pnov-ided in one or. more of the: members'to beclamped together. r

/ A plurality ofl suitably positioned clampin g boltsmay be provided,.if desired This invention may ivithiadyanta-ge be ap plied as a'meansfor connecting.- in a readily detachable'manuer, the-sepanal le parts of a sectional boat or punt, asillu-strated in l i'grures-Q, and' l. v V

A boat of the above type may comprise three separable sections 1:2, 13* andv 'l- 'l-c each embodying curved transverse 'endframe members-12a, 13a, and 14a spaced apart: and connected by longitudinal frame members 1%, 13b and 1&7), an outer covering 15' of plywood, sheet metalor othersuitable flexible material beingistretched transversely across I each of thesaidtframes; Each extremity of the boat, may be comprised by substantially U-shapedframe member 16 and an' upper transverse frame'member 17 secured-athereto, a suitablyshaped flat sheet 18 of the covering material. being; secured: across each ofi the said end frames; 7

The end portions of theboat may be se-- oured by s'crewsgbolts orothersuitablemeans and the covering may be-securedzto the:frame Themeansx described. above,

in a similar manner: A. detachable keel 19 and rudder 19a, indicated in dotted lines, may also be provided and one or more Wire rod or other stretching members (not shown) conveniently having associated screw devices, may be connected to theendportionsalit; and tightened toimpart rigidity to tlieboaii.

Rubber or other packing strips may be provided at the joints 20 or, alternatively, this-may be-ai spigot and secliet or tongue or. groove. joint, the object, being to render the said joint' Water-tight.

Connecting means according to the presentinventioa may be-provided atfbothi extremities of'the central section 18 oftlie boat to connect the saida section in a Water-tight mannerkto the front. andirean sections: 1i2and 14:- The curved endframe mcmbersItSa are accommodated within! the similarly shaped end frame members 12a andflsa oi thefront and rear sections of thezboat respectively.- andeach; connecting: means comprises an outer substantially rigid straps3'and inner curvedleait springsttas deseribedinconnection with the arrangement shown in Figure 1.

Upon each nut 11; being: tightened upon its bolt 7, the inner rame members of theccntrial? section 13 are clanmedtightly upon the eudi 'iinamexmembers, of the front andwrear sectionsof" the boatiand water is prevented from gaining, accessto the interior of the craft. 1 v

The extremities of the leaf spring la-may be: suitably: bent and; shaped: as shown toconstitute row locks and the extremities of the lezrfi. pring-Atr may, bebentas shown in: Figunesttfo, support t he'transnerse seat members Q-hwhiclnalso: ensure the lateral stability of the boats? The boat may be'propelled by, means; ofa smalh out-board: motor uuit or a sail., oars, paddles or panting pole-may be provided in connection: therewith: A ltcnnatively, the boat may be towed.
